摘　　要：目的利用磁共振探讨脑膜瘤瘤周水肿与脑膜瘤病理亚型之间的关系。方法收集本院经手术病理证实的脑膜瘤患者224例，所有患者术前均行MRI平扫及增强检查。结果本组224例脑膜瘤中，瘤周水肿的发生率自高而低排序的脑膜瘤病理亚型分别是：血管瘤型、微囊型、砂粒体型、上皮型、混合型和纤维型；瘤周水肿的最大径值自高而低排序的肿瘤病理亚型分别为：血管瘤型、微囊型、上皮型、砂粒体型、混合型、纤维型。横纹肌型、脊索型及乳头型脑膜瘤未见瘤周水肿。经Fisher确切概率法计算，不同脑膜瘤病理亚型之间水肿发生率差异无统计学意义（P=O．290）。结论脑膜瘤瘤周水肿的有无及水肿程度与肿瘤病理亚型无关。Abstract：Objective To study the relationship between peritumeral edema and pathological subtype in menNgIomas on MRL. Methods 224 patients with meningiomas proven histologically were studied by MRI. Results All of our series of 224 cases of men- ingiomas, the incidence of peritumoral edema was as following（in descending order） ： angiomatous, microcystic, psammomatous, me- ningothelial, mixed, fibrous subtype of meningioma; the degree of peritumoral edema was as following（in descending order）： angio- matous, microeystic, meningothelial, psammomatous, mixed, fibrous subtype of meningioma. But in rhabdoid, chordoid and papillary subtype of meningioma, peritumoral edema could not be found. By means of the Fisher exact probability method for calculating per- itumoral edema,P value was 0.290（no statistical significance）, peritumoral edema incidence was indifferent between different patho- logical subtype. Conclusion The peritumoral edema is not related to the pathological subtype of meningioma.
